I didn't do the ones you mention as they were made by other people and I have yet to contact them. I dont imagine they'd have an issue with you hosting them, but I didn't want to speak for them. As for updates, best to change over the Standard shuttle, the IAV106 shuttle and shuttlebay 2 rar files for the ones found on my site. I wouldn't bother keeping the old versions, they will contain errors or textures that I fixed in the new releases.

I have replaced these, but in the case of the Shuttlebay and the Standard shuttle, I have kept the old conversions as these have drawn more downloads over the years so I assume people are interested in those formats. I have added a note to indicate they are outdated. Is that ok with you?
